CONCAT ERROR(S) when running CN algorithm

I have the right packages installed and the correct Python version, so why does this error come up when running the CN algorithm?

MERGE ERROR(S) AT: /burg/home/sgg2140/communitynotes/sourcecode/scoring/pflip_plus_model.py, in _compute_scoring_cutoff, at line 348: scoringCutoff = scoringCutoff.merge(cutoffByRatings[[c.noteIdKey, "ratingMin"]])

Start in sourcecode/scoring/pflip_plus_model.py at _compute_scoring_cutoff, especially the merge on line 348, and reproduce the CN algorithm run shown in the traceback. Trace the types of the noteId merge keys and check the assertion at line 349; the issue is done when the merge completes without PandasTypeError and the assertion passes.
